Italian lighting manufacturer Arredoluce was an important proponent of postwar Italian lighting design and was founded by designer-entrepreneur Angelo Lelli (sometimes written Lelii). Lelli is thought to have established Arredoluce in 1947, the year after his lamp designs were included in the well-regarded Domus magazine.

Although some sources state that Arredoluce existed as early as 1939, it is improbable that the company was able to manufacture during Italy's involvement in World War II, and most sources therefore agree that a postwar date of establishment is more likely.

In addition to owning Arredoluce, Lelli also designed prolifically for his company for many years, and his modernist aesthetic undoubtedly played a role in bringing Italian lighting design to the international stage in the 1950s and 1960s.

Perhaps Lelli’s best known design for Arredoluce is the Model 12128 "Triennale", a three-armed floor lamp (1947, according to most Italian sources, or 1951-53 from other sources) exhibited at a postwar Triennale. The design was also licensed in the United States by Richards-Morgenthau for the Raymor Corporation.

Lelli continued to design and run Arredoluce until its closure in 1979. Today, Arredoluce’s designs are well-received on the vintage market, many of which are highly-sought after by Italian design enthusiasts and lighting collectors alike.
